No stuffing equals less mess and more fun. We took out all the extra fluff from these durable toys and stuffed them with what matters most: Invincibles Squeakers! These durable dog toys are filled with Outward Hound Invincibles Squeakers that Keep Squeakin’ If Punctured giving you and your dog more fun & extra squeak during playtime. Dogs just don’t like to play, they like to play hard! That’s why we made Invincibles Geckos with a Chew Shield layer and strong binding to help keep tough chewers playing & pet parents happy!
